[HELP] looping with floating number

i m trying to do an arithmetic series which is able to read in floating numbers. Yet i entered a problem with the looping.

Initially, i tried with inc instruction to increase my value in register cx by one b4 entering the second loop. Yet the value of cx will multiply itself with 1000, As result the loop can't run properly.

Then, i tried with another way. I declare a variable COUNTER and initiate COUNTER as 0. I move value one into the counter b4 entering the second loop.
mov eax, counter


Yet the same problem still occur.
